I need "ethernet controller" drivers for Li2727 for XP. These are the last drivers I have left to finally finish this part of my new notebook installation process. I tried some of the drivers I found here, but they wouldn't work, maybe they are not suitable for my model.

I had the same problem. And I was going crazy!
Install the XP drivers for Atheros AR5006EG, then download from fujitsu-siemens the Amilo LI2727 launch manager:

Hope it will work for you as it worked for me
